| embryo | <embryology, gynaecology> In animals, those derivatives of the fertilized ovum that eventually become the offspring, during their period of most rapid development, i.e., after the long axis appears until all major structures are represented. In man, the developing organism is an embryo from about two weeks after fertilization to the end of seventh or eighth week. Origin: Gr. Embryon (18 Nov 1997) |
